Line protection MCCB, 630 A frame, 242 kA at 240 V
The SENTRON 3VA2463-6HN32-0KB0 is a 3-pole molded case circuit breaker rated for 630 A continuous at 40 °C, with a maximum breaking capacity of 242 kA at 240 V and 187 kA at 415 V — built for line protection in high-fault industrial distribution. Current production; the lifecycle stage is marked current, so it remains an active catalog line for new panel builds and replacement duty.
Breaking capacity and derating
Breaking capacity drops from 242 kA at 240 V to 187 kA at 415 V and 440 V, then to 121 kA at 500 V, and 9 kA at 690 V — the 690 V figure is the weak point; verify the available fault current at that voltage before specifying. Continuous current derates with ambient temperature: 630 A at 40 °C, 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. For a 40 °C panel, the 630 A frame is the headline rating; above that, apply the derate curve.
Physical fit and auxiliary options
Dimensions: 248 mm high, 138 mm wide, 110 mm deep — a standard MCCB footprint for a 630 A frame. Panel cutout and mounting hole pattern should match the SENTRON 3VA series; verify against the existing backpanel layout. Comes with 2 auxiliary switches (HP) and a shunt trip release (STL) factory-fitted — no need to order those as separate accessories for this variant. No undervoltage release, no ground-fault monitoring, no communication module on this code.
Sourcing and compliance
Maximum power loss is 162 W; operating temperature range -25 °C to 70 °C, storage -40 °C to 80 °C. The part carries a voltage trigger (yes) and a trip indicator (no) — the shunt trip provides remote tripping capability.
